CBSE Class 10 Social Science Lifelines of National Economy MCQs Set 06

Answer: (c) Pipelines

Explanation:
1. Pipelines carry goods (liquids, gases, and even solids in slurry form) directly from source to destination through a continuous, enclosed system.
2. Since the goods never have to be transferred between vehicles or vessels along the way, there is no transshipment loss or delay.

Teacher's Note:
a) Transshipment means moving goods from one vehicle to another — pipelines avoid this entirely.
b) Pipelines carry petroleum, natural gas and even solids in slurry form.

Answer: (c) NHAI

Explanation:
1. National Highways are the primary road system linking the extreme parts of the country.
2. They are laid and maintained by the National Highways Authority of India (NHAI).

Teacher's Note:
a) Don't confuse NHAI (National Highways) with PWD (State Highways) or Zila Parishad (District Roads).
b) Each road category in India has its own dedicated maintaining authority.

Answer: (a) Metalled

Explanation:
1. Metalled roads are constructed with a hard surface (such as asphalt or concrete) and can be used in all weather conditions.
2. Un-metalled roads, in contrast, can become unusable during the rainy season.

Teacher's Note:
a) Metalled = surfaced/paved; un-metalled = unpaved, weather-dependent.

Answer: (a) Srinagar and Kanyakumari

Explanation:
1. The North-South Corridor is one of the major highway projects connecting Srinagar in the north to Kanyakumari in the south.

Teacher's Note:
a) Pair this with the East-West Corridor (Silchar to Porbandar) for a complete picture of India's major highway corridors.

Answer: (d) East-West

Explanation:
1. The East-West Corridor connects Silchar (in the north-east, Assam) to Porbandar (in the west, Gujarat).

Teacher's Note:
a) Together, the North-South and East-West Corridors form the major cross-country highway network, alongside the Golden Quadrilateral.

Answer: (a) Sher Shah Suri Marg

Explanation:
1. National Highway No. 1, connecting Delhi and Amritsar, is also known as the Sher Shah Suri Marg.

Teacher's Note:
a) Sher Shah Suri Marg is a historic name, dating back to Sher Shah Suri's original road network.

Answer: (a) Zila Parishad

Explanation:
1. District roads connect the district headquarters with other places within the district.
2. They are maintained by the Zila Parishad, the district-level local government body.

Teacher's Note:
a) Remember the hierarchy: National Highways (NHAI) → State Highways (State PWD) → District Roads (Zila Parishad).

Answer: (c) Jammu and Kashmir

Explanation:
1. Road density depends heavily on terrain. Jammu and Kashmir's mountainous terrain makes road construction difficult and costly, resulting in a lower road density compared to the plains.

Teacher's Note:
a) Contrast this directly with Kerala, which has the highest road density — a frequently paired comparison.

Answer: (a) Kerala

Explanation:
1. Kerala's dense population and relatively flat, accessible terrain have led it to develop the highest road density among Indian states.

Teacher's Note:
a) High population density and flat terrain generally support higher road density.

Answer: (d) 16

Explanation:
1. Indian Railways has been reorganised into 16 zones for better management and administration, as given in the source NCERT-based material.

Teacher's Note:
a) This question bank states 16 zones (the NCERT textbook figure); some more recent sources cite 17 after further reorganisation — check your own textbook's figure if in doubt.

Answer: (b) Slurry

Explanation:
1. Solid materials, such as coal, can be crushed, mixed with water to form a slurry, and then pumped through pipelines to their destination.

Teacher's Note:
a) Slurry transport is a good example of how pipelines aren't limited to just liquids and gases.

Answer: (b) Waterways

Explanation:
1. Waterways require no fuel-intensive propulsion comparable to air transport and can carry very heavy and bulky cargo at low cost, making them the cheapest mode of transport.

Teacher's Note:
a) Remember the order from cheapest to most expensive: Waterways < Railways < Roadways < Airways (roughly).

Answer: (d) Kochi

Explanation:
1. Along India's western coastline, Kochi (Cochin), in Kerala, is the southernmost major port, making it the extreme south-western port.

Teacher's Note:
a) Kandla, at the other end, is the northernmost major port on the west coast.

Answer: (c) Tuticorin

Explanation:
1. On India's eastern coastline, Tuticorin, in Tamil Nadu, is the southernmost major port.

Teacher's Note:
a) Pairs with the previous question — Kochi (west) and Tuticorin (east) are the two southernmost major ports.

Answer: (a) Chennai

Explanation:
1. Chennai (Madras) port is an artificial harbour and one of the oldest ports in the country, built by the British in the 17th century.

Teacher's Note:
a) ‘Artificial’ means a man-made harbour, as opposed to a naturally sheltered one like Mumbai's.

Answer: (a) Railways

Explanation:
1. These three features — principal mode for freight and passengers, enabling long-distance travel for varied purposes, and binding the economic life of the country — are the textbook description of Indian Railways.

Teacher's Note:
a) This description is a near-direct paraphrase of the NCERT chapter's own words on railways — learn it as a model answer.

Answer: (d) Varanasi and Kanyakumari

Explanation:
1. National Highway 7, one of the longest in India, connects Varanasi in Uttar Pradesh to Kanyakumari in Tamil Nadu.

Teacher's Note:
a) This is the longest National Highway by this source's reckoning — a frequently tested specific fact.

Answer: (c) Silchar

Explanation:
1. The East-West Corridor runs from Silchar (Assam) in the east to Porbandar (Gujarat) in the west, so Silchar is its eastern terminal.

Teacher's Note:
a) Silchar (east) and Porbandar (west) — learn this pair together with the North-South Corridor's Srinagar-Kanyakumari pair.

Answer: (a) Haldia

Explanation:
1. Haldia port was developed downstream of Kolkata specifically to ease congestion at the Kolkata port.

Teacher's Note:
a) Similarly, Jawaharlal Nehru Port (Nhava Sheva) was developed to relieve pressure on Mumbai port — a useful parallel example.

Answer: (b) Landlocked countries

Explanation:
1. Countries without a coastline, such as Nepal and Bhutan, are called landlocked countries. They depend on neighbouring countries' ports for sea trade.

Teacher's Note:
a) India's ports, particularly Kolkata, serve as important gateways for landlocked neighbours like Nepal and Bhutan.

Answer: (b) 1953

Explanation:
1. Air transport in India was nationalised in 1953, bringing all airlines under government ownership and control at the time.

Teacher's Note:
a) 1953 is a specific date worth remembering alongside the formation of Air India as the national carrier.

Answer: (a) Kandla

Explanation:
1. Kandla port, in Gujarat, was developed soon after Independence specifically to reduce the burden on Mumbai port, especially after the loss of Karachi port to Pakistan at Partition.

Teacher's Note:
a) This question links India's post-Partition port planning to its loss of Karachi — a useful historical connection.

Answer: (c) Jawaharlal Nehru port

Explanation:
1. Jawaharlal Nehru Port (Nhava Sheva), near Mumbai, was specifically developed to decongest Mumbai port while continuing to serve the same hinterland.

Teacher's Note:
a) Note the difference from Kandla: Kandla serves a different region altogether, while JN Port serves Mumbai's own region.

Answer: (c) Central Public Works Department

Explanation:
1. CPWD stands for Central Public Works Department, the authority responsible for maintaining National Highways in India.

Teacher's Note:
a) CPWD (National Highways) is distinct from the State PWD, which maintains State Highways.

Answer: (d) 34 km

Explanation:
1. India's first passenger train ran between Mumbai (Bombay) and Thane in 1853, a historic distance of 34 km.

Teacher's Note:
a) 1853 and the Mumbai-Thane route are specific facts frequently asked about Indian Railways' history.

Answer: (a) 7,516.6 km

Explanation:
1. India's coastline, including its mainland and island territories, is commonly cited as about 7,516.6 km long.

Teacher's Note:
a) This figure includes the Andaman & Nicobar and Lakshadweep island coastlines, not just the mainland.

Answer: (a) True — India has one of the largest road networks in the world

Explanation:
1. India's total road network is one of the largest in the world, aggregating to about 2.3 million km, second only to a small number of very large countries.

Teacher's Note:
a) This question was rephrased from the source's multiple-choice-by-country format into a true/false style for clarity, keeping the same underlying fact and answer.

Answer: (a) Golden Quadrilateral

Explanation:
1. This project is called the Golden Quadrilateral — a six-lane, high-quality highway connecting India's four largest metro cities, with a total length of about 5,846 km.

Teacher's Note:
a) Golden Quadrilateral = the 4 metro cities; North-South and East-West Corridors are separate, different projects.

Answer: (d) Pradhan Mantri Grameen Sadak Yojana

Explanation:
1. The Pradhan Mantri Grameen Sadak Yojana (PMGSY) was launched specifically to connect every village to a major town with an all-weather road.

Teacher's Note:
a) PMGSY targets rural connectivity specifically, unlike the Golden Quadrilateral or National Highways, which connect major cities.
